Then this is nothing more than animated shapes and lines. No magic one click plug-in here. Create a purple rectangle using the shape tools, animate the size and position, now do the same for an orange one, then one for every shape you see in the animation. The lines could be recreated with the pen tool and then Trim Paths used to animate the length. There's nothing more here than simple animation of shapes. Very basic stuff, just lots of it over and over.

If you're new to AE the please research using shape layers and animating their properties by typing "shape layer" in the Search Help field at the top right corner of AE and go through some of the training materials you'll find.
